Sift the flour in a bowl and make an orifice in the center, like a ¨volcano¨ and add in the orifice the yeast and all the herbs, plus the butter and a tablespoon of salt. Now knead carefully and pour milk, mixing it gently until you get a soft and homogeneous dough.
With the help of a rolling pin, stretch the dough until you get 1 inch thick, and cut circles. Now let it rest for 30 minutes covering the circles with a cloth.
After that, beat an egg and with it brush the dough surface. Finally, sprinkle grated parmesan cheese on top and put it in the oven for 15 to 20 minutes, or until they brown.
